Filed: 1981-11-17
Abstract: An articulated erosion control system provides a flexing articulated mat comprising a plurality of blocks which interlock in a three dimensional fashion allowing a mat formed of the blocks to conform to changes in terrain. In the preferred embodiment there is provided at least one "lock block" (FIG. 1) having a plurality of open ended sockets spaced about the periphery thereof and at least one "key block" (FIG. 2) being connectable during operation to the lock block the key block providing a plurality of locking arms spaced about and integrally formed with a central portion of the key block. Connection of the lock block and the key block can be achieved by relative vertical movement of the key block towards the lock block when the key block locking arm is superimposed over the open ended socket of the lock block-the connection being completed when a portion of the locking arm occupies at least in part the space within the socket. The socket is narrowed at its intersection with the peripheral wall portion of the lock block. The tip portion of the key block locking arm is enlarged thus disallowing relative motion between the key block and the lock block in a generally horizontal direction once the locking integral arm and socket are connected. In the preferred embodiment, the key block and lock block are each integrally formed-being, for example, of concrete or the like material. The blocks may have wave energy absorbing elements projecting from their upper surfaces.

Title: Device for removing gaseous components and/or solid impurities present in a gaseous fluid flow.
IPC: B01D50/00
Filed: 1982-02-23
Abstract: The invention concerns a means for removing gaseous components and/or solid impurities present in a gaseous fluid flow. The means (10) comprises a frame structure (11, 12), a fluid flow inlet connector (13), disposed within the frame structure (11, 12) a scrubber means (15), an exit connector (14) for carrying off the purified fluid flow, and a connector (20) for introducing scrubbing liquid into the means (10) and contacting it with the fluid flow. The scrubbing liquid exit flow has been disposed to pass through the fluid flow inlet connector (13) in opposite direction with reference to the fluid flow. The end region (21) adjacent to the scrubber means (15) of the fluid flow inlet connector (13) has a diminishing cross sectional diameter to the purpose of accelerating the flowing fluid flow before the fluid flow enters the scrubber means (15). The inlet connector (13) has been provided with holes (22) which have been adapted to receive into the inlet connector (13) the return flow of the scrubbing liquid. The holes (22) have been disposed in that region of the inlet connector (13) where the flow of the fluid flow is not accelerated, whereby the scrubbing liquid return flow within the inlet connector (13) is prevented from being entrained with the fluid flow and produces pre-purification of the fluid flow.

Title: Coupling device, particularly for looms.
IPC: D03C1/00
Filed: 1982-06-25
Abstract: In a coupling arrangement for use in a textile machine, a drive shaft can be intermittently rotated and a connecting member encircles and is connected to the drive shaft by an eccentric hoop located between them. A coupling key is displaceable between a coupling recess associated with the drive shaft and a coupling recess associated with the connecting member. The coupling key is retained in the recesses by lead cams. A shifting ring displaces the coupling ring alternately between the coupling recesses. The shifting member can be pivoted between two positions and a spring biases it into one of the positions. A control device moves the shifting member between its two positions. The control device includes a rotatable shaft with a rocking lever fixed to it. The rocking lever engages the shifting member for moving it from one position to the other against the biasing action of the spring. The control device includes a control part and based on the state of the control part the shifting member can be moved or held in place. The rocking lever performs one reciprocal motion for each cycle of a shedding unit and, accordingly, during each cycle the control of the shifting ring is effected for locating it in one of its positions.

Title: Simulated grass playing field surface with rubber particle layer and sand layer
IPC: E01C13/08
Filed: 1983-07-19
Abstract: A playing field surface is formed of a synthetic fiber carpet, having generally upright pile fibers, upon which is applied a particulate covering.

Title: Process for the hydroxylation of the aromatic nucleus of phenol or phenol-derivatives.
IPC: C07C37/60
Filed: 1984-09-26
Abstract: The production of solutions of hydrogen peroxide in phenol or its derivatives, e.g. hydrocarbyl substituted phenols, halo substituted phenols or phenol ethers, is carried out in a single step. Practically no loss of hydrogen peroxide occurs since a total distillation of hydrogen peroxide together with phenol or phenol derivative is avoided. Simultaneously the solutions obtained are practically free from water. The mixture of phenol or phenol derivative and aqueous hydrogen peroxide is treated with a material that boils below the boiling point of hydrogen peroxide, phenol or phenol derivative or forms an azeotrope with water that boils below the boiling point of hydrogen peroxide, phenol or phenol derivative and the water removed as an azeotrope. The solution of hydrogen peroxide in phenol or phenol derivative which remains behind is suitable for carrying out oxidation reactions and above all, also for hydroxylation reactions.
